LaTeX Equation Renderer
Render LaTeX math equations with live preview.
About This Tool
LaTeX Renderer is a free online tool for writing and previewing LaTeX math equations using KaTeX — the fast, high-quality browser-based TeX rendering engine developed by Khan Academy. Enter any LaTeX expression and see it rendered with publication-quality typography in real time. Supports display and inline modes, adjustable font sizes, and the full range of standard LaTeX math commands.
KaTeX renders LaTeX math at near-native TeX quality, supporting fractions, integrals, summations, Greek letters, matrices, aligned equations, and all common mathematical notation. Rendering happens entirely in the browser — no files are sent anywhere, and there is no server delay. Syntax errors in your LaTeX expression are caught and reported immediately.
LaTeX Renderer is most useful for students and academics writing mathematical equations, researchers preparing formulas for papers or slides, educators creating math content for online courses, and developers testing KaTeX or MathJax expressions before embedding them in web applications.

FAQ
What LaTeX commands are supported?
All standard LaTeX math commands including fractions, integrals, matrices, Greek letters, and more via KaTeX.
What is display mode?
Display mode renders equations centered on their own line (like \[...\]), while inline mode fits within text (like $...$).
What is KaTeX?
KaTeX is a fast, open-source JavaScript library for rendering LaTeX math in the browser, developed by Khan Academy. It supports a comprehensive subset of TeX/LaTeX math commands and renders with publication-quality typography.
Can I use this to render LaTeX equations for my website?
This tool is for previewing and rendering individual equations. To render LaTeX on a website, integrate KaTeX or MathJax directly — they are open-source libraries with detailed installation guides.
Does it support LaTeX environments like matrices or aligned equations?
Yes. KaTeX supports \begin{matrix}, \begin{pmatrix}, \begin{bmatrix}, \begin{aligned}, and other standard LaTeX math environments.
